All of it lives on Tumblr's servers, not yours. When a blog you follow deactivates, those posts vanish from your likes forever. When Tumblr updates its policies, your content might suddenly be at risk. When you decide to leave the platform or simply want a local copy, extracting your data becomes a frustrating ordeal. Tumblr does offer a built-in export feature, but anyone who has used it knows the result: a chaotic archive of nested HTML files and folders. Finding a specific post means clicking through dozens of directories. Getting that data into a spreadsheet for actual use requires technical knowledge that most users simply don't have. This gap between wanting your data and actually having usable data is where most backup attempts fail. You download the archive, open it once, feel overwhelmed by the mess, and never touch it again. ## What This Extension Does Tumblr Exporter bridges that gap with a direct approach. Browse Tumblr normally, click export, get a clean file you can actually use. The extension works in your browser while you browse. Navigate to your dashboard, your blog archive, your likes page, or any public blog. Click the extension icon, choose your settings, and download. No waiting for email links. No extracting zip files. No parsing HTML. ### Export Your Own Blog Every original post you've written. Every reblog you've added commentary to. Text content, image URLs, tags, timestamps, note counts. The extension reads this data as you scroll through your archive, capturing everything Tumblr displays. When you're ready, export to a spreadsheet where each post becomes a row and each data point becomes a column. Sort by date. Filter by tag. Search for specific text. Your entire posting history becomes searchable and organized. ### Save Your Liked Posts Your likes collection tells a story. Years of art that inspired you, writing that moved you, jokes that made you laugh, conversations that made you think. This collection exists nowhere else. But liked posts are fragile. When the original poster deactivates their blog or deletes that post, it vanishes from your likes too. No warning, no archive, no way to recover it. Artists leave platforms. People delete accounts. Content disappears constantly. Tumblr Exporter lets you capture liked posts while they still exist. The same data available for your own posts can be exported from your likes: content, author information, tags, timestamps, URLs. Build a personal archive before posts disappear. ### Archive Any Public Blog Found a blog with content worth preserving? An artist whose work you admire, a writer whose posts you want to reference, an archive that might not exist forever. If you can view it on Tumblr, you can export it. Navigate to the blog, scroll through posts to load them, and export. Works for active blogs and inactive ones alike. ## Export Formats That Actually Work Raw data means nothing if you can't use it. The extension outputs files designed for real human use. **CSV Format** CSV files open in virtually any spreadsheet application. Excel, Google Sheets, Apple Numbers, LibreOffice Calc. Each post becomes a row. Each data field becomes a column. No special software required. With your data in spreadsheet form, you can sort posts chronologically, filter by specific tags, search for text across thousands of posts, or analyze patterns in your posting history. Basic spreadsheet skills unlock your entire archive. **Excel Format** For users who work primarily in Microsoft Excel, native .xlsx format offers advantages. Better handling of special characters and unicode, preserved formatting, support for larger datasets, and full compatibility with Excel's feature set. **JSON Format** Technical users who want to process data programmatically get clean JSON output. Nested structures like reblog chains and tag arrays export properly, ready for scripting or database import. ## What Data Can You Export Tumblr posts contain more metadata than most users realize. The extension captures: **Post Information** - Full post content and summary text - Post URL and Tumblr permalink - Post type (text, photo, quote, link, video, audio) - Publication date and timestamp - Current state and visibility **Engagement Data** - Total note count - Like, reblog, and reply counts - Tags attached to the post **Media Content** - URLs for images and media files - Media type and count - Content classifications **Blog Information** - Blog name and display title - Blog description and avatar URL - Theme colors and settings - Follow status and permissions **Community Data** - Community membership information - Reblog chain details - Original poster attribution You control which fields appear in your export. Include everything for comprehensive backups, or select only the fields you need for cleaner output. ## Common Use Cases **Leaving Tumblr** Planning to migrate your online presence elsewhere? Export your content first. Spreadsheet format makes it easy to review what you have, decide what's worth keeping, and transfer content to a new platform or personal archive. **Personal Backup** Some users simply want insurance. Knowing your content exists on your own computer, in a format you control, provides peace of mind. If anything happens to your Tumblr account, you haven't lost years of work. **Finding Old Content** Tumblr's search functionality has limits, especially for older posts. Export your archive to a spreadsheet and use Ctrl+F to find anything instantly. That quote you reblogged three years ago? Found in seconds. **Research and Analysis** Researchers studying online communities, fan culture, or social media trends can export public content for analysis. Get data into the format your methodology requires. ## Technical Details **How It Works** The extension reads page content that Tumblr displays to your browser. When you scroll through a blog or dashboard, Tumblr loads posts dynamically. The extension captures data from these loaded posts and holds it in memory until you export. This means the extension sees exactly what you see. Posts visible to you can be exported. Posts you can't access remain inaccessible. No special permissions, no API keys, no authentication required beyond being logged into Tumblr. **Privacy** All data processing happens locally in your browser. Post data goes directly from Tumblr's page to your exported file. Nothing passes through external servers. Nothing gets stored in the cloud. When you close the tab, unexported data disappears. **Performance** For large exports, scroll through content first to let Tumblr load posts. The extension collects data as fast as Tumblr serves it. Very large archives may require patience or breaking exports into batches. ## Limitations **Media Files** The extension exports URLs to images and media, not the actual files. Your export contains links showing where each image is hosted. Downloading the actual image files requires additional steps using those URLs. **Private Content** If you can't see a post on Tumblr, the extension can't export it. Private blogs, deleted posts, and content from accounts you don't follow remain inaccessible. **Point-in-Time Exports** Each export captures current data. New posts made after an export require a new export to capture. There's no automatic sync or continuous backup feature. ## Getting Started Install the extension from Chrome Web Store. Navigate to any Tumblr page with posts. Click the extension icon to open the export panel. Select which data fields to include, choose your output format, and click export. For comprehensive backups, scroll through your content first to load more posts into the page, then export. The extension captures whatever Tumblr has loaded in your browser. ## Why This Matters Digital content is more fragile than people realize. Platforms change. Policies shift. Accounts get suspended or deleted. Blogs deactivate without warning. Content that seems permanent today might be gone tomorrow. Your Tumblr presence represents real creative work. Posts you wrote, art you curated, conversations you participated in. This content has value beyond its platform. Taking backups isn't paranoid. It's acknowledging that platforms are temporary custodians of your data, not permanent archives. The extension makes backing up simple enough that there's no reason not to. Your blog. Your backup. Your control.
